The Fallen Legacies (Mentioned)Edit
Upon showing signs of weakeness following the apparantly failed memory transfer experiment and failing to kill Number Two, Adamus' father Andrakkus threatens to send him to the mountain base to take part in training, something that his wife manages to talk him out of. Adamus notes how labourous this training would be.
Both Sam and Four enter the base using the Xitharis charged with Six's Invisibility, in order to recover his Loric Chest. They are unable to locate the chest until Four suggests that it would be hidden in the most dangerous place of the cave, the animal pen. Here they find the chest, along with another chest and Four battles a large ape creature and causes a large explosion that erupts throughout most of the base in order to escape. In the tunnels they find rows of prison cells, one bursts open and they meet Number Nine who had been imprisoned there for a long time. Nine is reunited with his chest and the group fight the oncoming mogadorians and creatures.
The Rise of Nine (Seen)Edit
After escaping the base, Nine and Four make it a few miles before the truck runs out of gas. They hide in an abandoned house. Once Four has recovered from hitting the force field, Bernie Kosar leads him to a peak where they are able to see the blue light of the force field. Four immediately plans to return but, after using the communicator in Nine's chest, they are soon captured by the FBI.
